Dave Armstrong has posted a blog entry (and a new one here) explaining how one anti-Catholic operates as he criticizes Catholics. Interesting read! Guys like this really ought to fix the real holes in his own bucket before trying to find perceived holes in someone else's (Matt 7:3-5). An earlier post by Dave on the same topic can be read here.
In the meantime we are doing some very interesting research on the background of the quote in question.
